Description

FACEMASK ASSEMBLIES WITH MULTI-MOUNTSCross-Reference to Related

[0001] This application is related to and claims priority benefits from U.S. Patent Application Serial No. 63 / 592,316 filed October 23, 2024, entitled “Facemask Assemblies with Multi-Mounts”. The ‘316 application is hereby incorporated by reference herein in its entiretyField of the Invention

[0002] The present disclosure relates to facemask assemblies. In particular the disclosure relates to facemask assemblies with multi-mounts. More particularly, the disclosure relates to facemask assemblies with a core frame, a facial skirt, a filter assembly, a front section, and / or multi-mounts configured to attach strap assemblies and / or accessories to the facemask assembly.

[0003] Facemask assemblies are designed to protect the wearer and others in the vicinity of the wearer from airborne pathogens including bacteria and viruses. Facemasks are typically worn over the mouth and nose and can incorporate a form of eye protection.

[0004] Masks can be used in environments with high levels of airborne particulates and / or allergens where the wearer wishes to not inhale said particulates. To effectively reduce a wearer’s exposure to airborne substances, a respiratory protection device needs to fit well and effectively filter out said substances.

[0005] Preventing inhalation and contact with airborne pathogens and environmental allergens is not only important in environments that require high levels of air purity, such as hospitals, but also in homes of people suffering fromallergies. Additionally, wearers suffering from respiratoiy infections can benefit from the filter capture of pathogens and allergens when out in public. Masks are also often worn by users working in environments including particulate in the air, for instance in construction sites and work zones.

[0006] Conventional masks can be attached to the wearer’s head by means of tie straps, elastic straps headbands, and / or nonadjustable holes cut into the mask designed to fit around the wearer’s ear. Alternatively, masks can be fastened using elastic straps around the head or ears. Rectangular cross-sectional elastics are often used in one-size-fits-all nonadjustable masks. These masks are often uncomfortable as they can stretch and / or pinch the skin around the ears and back of the head. Similarly, conventional single and double strap systems are often uncomfortable and complicated to adjust to an individual face. This can lead to failure to seal the mask to the face, rendering the mask useless.

[0007] In addition, conventional masks are often required to be disposable as the strapping material tends to capture skin excretions as well as airborne particulates and pathogens and is difficult to clean.

[0008] To be effective in reducing a wearer’s exposure to airborne substances, a respiratoiy protection device needs to have a sufficient fit as well as high filtration efficiency. However, conventional masks often provide a poor seal between the mask and the face and / or do not provide a way to easily determine if a proper seal has been formed.

[0009] What is needed are facemask assemblies that are easily disinfected / sterilized, are readily adjustable (including the ability to be readily tilted), provide a proper seal on a variety of face sizes and shapes, have a seal that can be easily verified, are customizable with various attachments, and / or provide a way to keep the inside of the mask from contamination while not in use.Summary of the Invention

[0042] In some embodiments, facemask assembly 10 can be held together using core frame 12 (shown in FIG. 2). In some embodiments, facial skirt 14, filter assembly 16 and / or front section 18 can be attached to core frame 12.

[0043] In some embodiments, core frame 12 can include one or more attachment members 22 configured to attach facial skirt 14 and / or front section 18 to core frame 12. In some embodiments, attachment members 22 protrude from an outer surface of core frame 12. In some embodiments, core frame 12 can include at least two attachments members 22. In some embodiments, attachment members 22 can be located on opposite sides of core frame 12. For example, in some embodiments, such as the one shown in FIG. 1, core frame 12 can include attachment member 22 on either side of core frame 12. In some embodiments, attachment members 22 can serve as vents.

[0044] In some embodiments, such as shown in FIG. 19, attachment members 22 act as vents. In some embodiments, at least one attachment member includes a one-way valve to allow air to flow in only one direction. In the embodiment shown in FIG. 19, one attachment member 22 is located on the lower section of core frame 12 and incorporates a valve which prevents, or at least reduces the chance of air from entering the mask but allows air to exit the mask as shown by arrow 23. In some embodiments, airflow into and out of the mask, and resulting humidity, can be controlled by incorporating one or more valves into one or more attachment members.

[0045] In some embodiments, core frame 12 includes core frame opening 24 defined by the perimeter of core frame 12. In some embodiments, core frame opening 24 can be configured to receive filter assembly 16.

[0046] In some embodiments, core frame 12 can be made of a rigid or semirigid material, such as, but not limited to, various polymers, elastomers, plastics, rubbers, and / or silicones. In some embodiments, to assemble facemask assembly 10, facial skirt 14 is attached to core frame 12 using attachment members 22. In some embodiments, filter assembly 16 can be placed within core frame opening 24. In some embodiments, front section 18 can then be placed over filter assembly 16 and attached to core frame 12 using attachment members 22. In some embodiments, core frame 12 can contact filter assembly 16 (see FIGS. 2-3) and front section 18 when facemask assembly 10 is assembled, sealing the facemask together.

[0047] In some embodiments, facemask assembly 10 includes facial skirt 14. In some embodiments, facial skirt 14 has elastic properties and contacts the face of a wearer. In some embodiments, facial skirt 14 can be constructed from materials such as, but not limited to, soft silicone that conforms to the wearer’s face and can create a seal with the wearer’s skin. In some embodiments, facial skirt 14 can be produced via additive manufacturing to allow for greatercustomization. In some embodiments, facial skirt 14 includes an inner perimeter defining an opening at first end 26. In some embodiments, first end 26 can be sized to fit over core frame 12.

In some embodiments, the outer perimeter at a second end 28 of facial skirt 14 defines an opening formed therein that fits over the nose and ar ound the mouth of a wearer, sealing facemask assembly 10 to the wearer’s face.

[0048] In some embodiments, facial skirt 14 can be attached to core frame 12. For example, in some embodiments, facial skirt 14 can include facial skirt apertures 30 configured to receive core frame attachment members 22. In some embodiments, facial skirt apertures 30 are sized to correspond with the shape of attachment members 22. In some embodiments, facial skirt 14 includes a facial skirt aperture 30 for each attachment member 22 on core frame 12. In some embodiments, facial skirt 14 can be attached to core frame 12 via adhesive attachment. In some embodiments, facial skirt 14 and core frame 12 can be a unitary piece.

[0049] In some embodiments, facial skirt 14 can be attached to core frame 12 by inserting core frame 12 through second end 28 and pulling core frame 12 through facial skirt 14 until attachment members 22 enter facial skirt apertures 30. In some embodiments, facial skirt 14 can be stretched over core frame 12 such that attachment members 22 enter facial skirt apertures 30.

[0050] In some embodiments, such as shown in FIG. 17 and FIG. 18, core frame 112 incorporates a facial skirt directly into core frame 112 during the manufacturing process. In some embodiments, core frame 112 with the integrated facial skirt includes some, if not all, of the features of core frame 12 and / or facial skirt 14.

[0051] In some embodiments, such as shown in FIG. 17, front section 118 incorporates a filter assembly directly into front section 118 during themanufacturing process. In some embodiments, front section 118 with the integrated filter assembly includes some, if not all, of the features of front section 118 and / or filter assembly 16.

[0052] In some embodiments, facial skirt 14 can be customized to a specific wearer, such as for example via additive manufacturing. In some embodiments, facial skirt 14 can be configured to the unique facial topography of a specific wearer. Adjusting various properties of facial skirt 14 such as, but not limited to, its weight, length, width, depth, and / or the shape of the outer perimeter at second end 28 based on the distinct facial structure of the wearer, can create a facemask that optimally conforms to the wearer’s face and provides a seal with the skin. A customized facial skirt 14 can also maximize, or at least increase, wearer comfort.

[0053] In some embodiments, facial skirt 14, can be made from materials that balance wearer comfort with struct ural / functional properties: thickness, elasticity, flexibility, coefficient of friction, etc. The materials can provide structural integrity such that facial skirt 14 conforms to the contours of the wearer’s face and creates a seal with the skin. Tactile properties of facial skirt 14 such as smoothness and / or texture of the outer perimeter and / or other surfaces that contact the wearer’s skin can be adjusted. In some preferred embodiments, facial skirt 14 can be made from a silicone, silicone-based materials, thermal polyurethanes (TPU) and / or synthetic rubbers.

[0054] In at least some embodiments, facial skirt 14 includes multiple seallayers to protect various face shapes and sizes. In some embodiments, such as shown in FIG. 4, facial skirt 14 has two seal-layers, layer 32 and layer 34. In some embodiments, facial skirt 14 has three seal-layers. In some embodiments, facial skirt 14 has four seal-layers. In some embodiments, facial skirt 14 has five seal-layers. In some embodiments, facial skirt 14 has at least six seallayers.

[0055] In some embodiments, facemask assembly 10 includes filter assembly 16. Filter assembly 16 can be configured to hold filter material 40. In some embodiments, such as the one shown in FIG. 7, filter assembly 16 is made of a filter frame 42 and filter material 40. In some embodiments, filter assembly 16 can be attached to core frame 12. In some embodiments, filter frame 42 can be shaped to correspond with core frame opening 24 such that filter assembly 16 fits into core frame opening 24. In some embodiments, filter assembly 16 is attached to core frame 12 via a friction- fit. For example, in some embodiments, filter frame 42 can be made of a thermoplastic polyurethane (TPU), silicone, or thermoplastic vulcanizate (TPV) such that filter frame 42 contacts the inner surface of core frame 12 and is retained with friction forces. In some embodiments, filter assembly 16 can be attached to core frame 12 using other attachment means such as with, but not limited to, clips, adhesives, screws, bolts, magnets, and / or nuts. In some embodiments, filter assembly 16 is permanently affixed to core frame 12.

[0058] In some embodiments, filter assembly 16 is configured to accept a pleated filter material 40 (such as shown in FIG. 5). In some embodiments, filter material 40 is positioned between top piece 52 and bottom piece 54. In some embodiments, filter material 40 is initially flat and becomes pleated as it conforms to horizontal portions 56 and horizontal portions 58 of top piece 52 and bottom piece 54, respectively, when pressed between frame top piece 52 and bottom piece 54. For example, in some embodiments, top piece 52 caninclude flat horizontal portions 56 and bottom piece can include raised horizontal portions 58. Flat horizontal portion 56 and raised horizontal portions 58 can be arranged such that when top piece 52 and bottom piece 54 are pressed together, raised horizontal portions 58 fit in the spaces between flat horizontal portions 56. In this way, filter material 40 between top piece 52 and bottom piece 54 can be retained in a pleated shape. In some embodiments, top piece 52 and bottom piece 54 can include vertical portions such that when filter material 40 is sandwiched between top piece 52 and bottom piece 54 the pleats run vertically within filter frame 50. In at least some embodiments, the pleated shape increases the breathable surface area as well as increases the angularity of the oblique angle of attack experienced by an inhaled particulate and / or pathogen. In some embodiments, top piece 52 is not needed for the filter assembly 16 and instead, core frame 12 operates as the top piece.

[0059] In some embodiments, filter assembly 16 has a pleated / folded design that positions filter material 40 away from the wearer’s face, so that it does not interfere with talking and facial expressions, provides a large filtration area, is more breathable, and / or speeds the evaporation of moisture from within the mask. In some embodiments, filter material 40 filters over 94% of particulates.

[0060] In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 10% more than a flat filter positioned between the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 20% more than a flat filter positioned between the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 30% more than a flat filterpositioned between the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 40% more than a flat filter positioned between the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 50% more than a flat filter positioned between top piece the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 60% more than a flat filter positioned between the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 70% more than a flat filter positioned between the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 80% more than a flat filter positioned between the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 90% more than a flat filter positioned between the filter frame. In at least some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulates, viruses, and the like, by at least 100% more than a flat filter positioned between the filter frame.

[0061] In some embodiments, the use of a pleated filter between the filter frame increases the surface area of filter material available for interacting with the various particulate, viruses, and the like, by three to ten times (300% to 1,000%) more than a flat filter positioned between the filter frame.

[0062] In some embodiments, filter material 40 has a single active surface. In other embodiments, filter material 40 can have multiple active surfaces. In certain embodiments, the active material contains silver which acts as a biocidal element.
